Have you checked inside the fuel tank for any blockages at the connector drain hole where the fuel is fed to the engine as you could have some debris there.

Craftsman Leaf Blower will only rev up about 1/2 power at full throttle. Any suggestions?

If this is a two cycle engine there are adjustment screws that set the fuel mixture when the throttle is depressed.

Will not start after putting on new fuel filter and spark plug

This may seem silly, but if you put a new fuel filter in, did you drain the fuel and not put fresh fuel in the tank, and is the plug wire connected properly?

Good luck.

I have a 15.5 HP, Craftman lawn tractor. I'm having problem with it staying running. It will run just find for 20-30 minutes and then stop abruptly. I have changed the spark plug, oil, cleaned the air...


Check the Blade Safety Switch. Also check if the Carburettor requires a good cleaning and overhaul or not. After that check if there is any air leak or air in the fuel line.

Please accept the solution if it's helpful. Do get back to us for any further query.

Thanks for contacting

Have a 20 HP twin cylinder KOHLER engine on CRAFTSMAN mower.

If you are able...have someone do a compression check on the engine. Usually if a mower is loosing power and it is a twin cylinder engine, one of the headgaskets may be blown.
